管理者は LACP EtherChannels を使用して 2 つのスイッチを設定しましたが、スイッチ間でパケットが交換されていません。 理由は何ですか、そしてどうすれば問題を解決できますか? S1> enable S1# configure terminal S1(config)# interface port-channel 1 S1(config-if)# ip address 10.1.1.1 255.2 S1(config-if)# interface g2/0/0 S1(config-if)# no ip address S1(config-if)# channel-group 1 mode active S1(config-if)# exit S1(config)# interface g4/0/0 S1(config-if)# no ip address S1(config-if)# channel-group 1 mode active S2> enable S2# configure terminal S2(config)# interface port-channel 1 $2(config-if)# ip address 10.1.1.2 255.255.255.0 S2(config-if)# interface g2/0/0 $2(config-if)# no ip address $2(config-if)# channel-group 1 mode desirable S2(config-if)# exit S2(config)# interface g4/0/0 S2(config-if)# no ip address S2(config-if)# channel-group 1 mode desirable
正解:C
The correct answer is C because when S1 is configured with LACP (Link Aggregation Control Protocol), the channel group mode should be set to 'on' to force the interface to channel without LACP negotiation. This is based on the understanding of LACP operation within the Service Provider network infrastructures, where LACP is used to aggregate multiple network interfaces into a single logical link to increase bandwidth and provide redundancy.
